DISPENSING SYSTEM FOR DISPENSING MACHINE Russian patent published in 2011 - IPC B67C3/00 

FIELD: transport.

SUBSTANCE: hot product dispensing system comprises filling element with hydraulic channel to communicate with product reservoir, on one side, and to form dispensing zone, on its other side. Hydraulic channel is provided with hydraulic valve to switch from open position to closed one. Proposed system comprises first flow channel formed in filling element casing to communicate hydraulic channel section with accumulator channel shared by several filling elements. System incorporates second flow channel for cleaning and/or sterilising dispensing system communicated with washing chamber occupying proportioning zone. Flow channels incorporates valve controlled by pressure in appropriate flow channel. First valve arranged in first flow channel cam automatically open first flow channel with closed hydraulic valve with open hydraulic valve it closed it. Second flow channel incorporates second valve to close second flow channel, with hydraulic valve of second flow channel both open and closed, while at pressure exceeding that applied to second valve in fluid proportioning, it automatically opens second flow channel.

EFFECT: keeping filling element heated between dispensing intervals and allowing washing without disassembling dispensing system.
